ColdFusion Tag Handler Error

Question

I have a a cf page that creates a pdf which has been working for a while and after a server reboot this weekend it is now throwing the following error: (This is CF8)

The tag handler document does not have a setter for the 
attribute scaleToFit specified in the Tag Library Descriptor.

The error occurred in  line 149

147 :       </cfquery>
148 : 
149 :       <!--- Build PDF Document --->
150 :       <cfdocument format="pdf" name="Invoice" 
                    orientation="landscape" margintop="2" marginbottom=".8"
151 :       marginleft=".5" marginright=".5" fontembed="no" localurl="true">
